The two players of the game are vulnerable node
and the malicious nodes in the fog cluster.
Terrorists are able to intrude into a system connected to critical infrastructure through the most vulnerable node
among numerous nodes of allied nations.
When a mission changes, the highest degree neighbor may change from the most vulnerable node
to the least vulnerable node
If upgrading to the latest OS version is not possible, organizations are advised to take into account this attack vector in their threat model and to address it through smart separation of vulnerable nodes
from the rest of the network, in addition to other measures.
"They have offset their relative weakness versus the United States by using time and geography to their advantage and by focusing their weapons - and concept-development efforts on finding ways to attack vulnerable nodes
in US military operations," it said.
Since the sender S and receiver R are rational, the key problem is how to calculate the security-weight threshold to get the set of vulnerable nodes
BETWI always attacks the largest remaining GC and also chooses very vulnerable nodes
in each step, making the attack rather disruptive to the network.
This suggests that 10% of nodes with largest node degree are the most vulnerable nodes
in the network model, which means that the corresponding components in the infrastructure are vulnerable.
Weak nodes and strong nodes can be identified, thereby identifying the most vulnerable nodes
to be modified/ updated and those that, if not activated, could generate higher thresholds of uncertainty for a project.
Initially vulnerable nodes
are identified based on analysis of the input traffic by comparing the current traffic with the predefined set of traffic that was labelled as legitimate traffic which was observed over a period of time and stored in the form of a rule.
Global techniques improve security of the entire network by impeding attackers from finding the most vulnerable nodes
, suitable for injecting the malicious code thus converting them to zombies.
The small, turnkey appliance also interacts with many of the leading firewalls to control traffic to and from vulnerable nodes
